Anti-drop-off system for robot

Abstract

An anti-drop-off system for robot is provided, which mainly includes a detection unit, a control unit, a driving unit, a first determination and a first switching unit. The detection unit generates an anti-drop-off precaution signal when detecting that the robot will drop off if the robot keeps moving in the moving direction thereof. The control unit receives the anti-drop-off precaution signal and then transmits a moving control signal to the driving unit. If receiving the anti-drop-off precaution signal and the moving control signal, the first determination unit transmits a first interrupt signal to the first switching unit and further stops the control unit transmitting the moving control signal for controlling the robot to move in the direction which the robot will drop off to the driving unit in order to make real-time determination and prevent the robot from dropping off

What is claimed is: 
     
         1 . An anti-drop-off system for robot, comprising:
 a driving unit, disposed inside a robot to drive the robot to move;   a detection unit, disposed at one or both of a bottom and a peripheral of the robot, and configured to transmit a detection signal, wherein the detection signal is that the detection unit generates an anti-drop-off precaution signal when detecting the robot is going to drop off in a moving direction thereof;   a control unit, disposed inside the robot, connected to the detection unit and the driving unit, and configured to transmit a moving control signal to the driving unit to control the driving unit to drive the robot to move, wherein when the control unit receiving the anti-drop-off precaution signal, the control unit transmits an anti-drop-off control signal to the driving unit;   a first determination unit, disposed inside the robot and connected to the detection unit and the control unit, wherein when the first determination unit receiving the anti-drop-off precaution signal and the moving control signal for controlling the robot to move in a direction which the robot will drop off, the first determination transmits a first interrupt signal; and   a first switching unit, disposed inside the robot, between the control unit and the driving unit, and connected to the first determination unit, wherein when the first switching unit receiving the first interrupt signal, the first switching unit stops the control unit transmitting the moving control signal which drives the robot to move in the direction which the robot will drop off to the driving unit.   
     
     
         2 . The anti-drop-off system for robot of  claim 1 , wherein the moving control signal is a move-forward signal for driving the robot to move forward and the detection unit is disposed in front of the robot; the anti-drop-off precaution signal is move-forward anti-drop-off precaution signal for preventing the robot moving forward and then dropping off; when the control unit receiving the move-forward anti-drop-off signal, the control unit stops transmitting the move-forward signal and then transmitting the moving control signal to the robot again, wherein the moving control signal is changed to be a move-backward signal for driving the robot to move backward. 
     
     
         3 . The anti-drop-off system for robot of  claim 2 , wherein the moving control signal is a move-backward signal for driving the robot to move backward and the detection unit is disposed behind the robot; the anti-drop-off precaution signal is move-backward anti-drop-off precaution signal for preventing the robot moving backward and then dropping off; when the control unit receiving the move-backward anti-drop-off signal, the control unit stops transmitting the move-backward signal and then transmitting the moving control signal to the robot again, wherein the moving control signal is changed to be a move-forward signal for driving the robot to move forward. 
     
     
         4 . The anti-drop-off system for robot of  claim 3 , further comprising:
 a second determination unit, connected to the driving unit and the control unit, wherein when the second determination unit receiving a moving direction of the driving unit and the moving direction of the driving unit is different from a moving direction of the moving control signal, the second determination unit transmits a second interrupt signal; and   a second switching unit, wherein the driving unit is connected to a power supply unit disposed in the robot via the second switching unit, and the second switching unit is further connected to the second determination unit; when the second switching unit receiving the second interrupt signal, the second switching unit disconnects the driving unit from the power supply unit.
